Silicone is one of the best materials for the manufacture of sex toys because it is non-porous, phthalate free and hypoallergenic. Silicone sex toys are also non-toxic, odourless, tasteless, anti-allergic and are rigid enough to provide you with a good time whilst still being soft enough to be easily inserted into the anus or the vagina. Their hard-wearing and waterproof qualities also means that they can be heated or chilled and even washed in a dishwasher!
